I ate at a mexican place in Tulsa with some friends that I had never heard of before a few years ago. They told me it was great, but i thought it sounded retarded...it was a bunch of girls, though, so I let them do what they want. Anyway, we went there and I had a taco salad. That night I felt like I was going to die. My stomach filled up with gas so much so that I threw up air. Not like dry heaving, like my stomach was protruding largely out from under my ribcage and i violently vomitted air until it was back to normal size. Twice. It was awful. Then after that incident and many months of similar but less severe symptoms, we finally figured out that I had gotten some kind of terrible food poisoning (probably from that damn place) that had damaged my stomach's nerves. My stomach was almost entirely paralyzed. It took more than a year for it to repair itself to the point that it moved even close to the normal amount. Right now it's almost back to normal, but it's still a bit slow.
